Definitions

  • THIS INVENTION relates to a barrier system for removing water and solid contaminants from fuel before it is fed to an engine.
  • the internal combustion engine is susceptible to damage from water and contaminants in the fuel. Diesel engines are particularly prone to damage and it seems the more technologically advanced they become the more they are prone to this particular damage.
  • One current solution is to place a filter in the fuel line between the fuel tank and the engine.
  • the extremely high flow rates in what are called common-rail diesel engines cause many problems. In these systems most of the fuel pumped through the fuel line is returned to the tank so the in-line filters filter the same fuel many time over. These in-line fuel filters are not fully able to cope with the high flow rates and the volumes of fuel that pass through them.
  • the present invention provides a means of protecting an engine from the water damage which may arise from filling the engine's fuel tank from a contaminated fuel source.
  • a barrier unit for fitting to the filler opening of a fuel tank for preventing water and solid contaminants from entering the fuel tank with the fuel, the barrier unit comprising a liner of a material which permits fuel to pass through it but retains water and solid
  • the liner being closed at its lower end and open at its upper end to form an inlet to the liner so that fuel being pumped to the tank enters the liner at its upper end, there being a perforated cylindrical support which sheaths the liner and prevents the liner being burst by the pressure of the fuel flowing into it.
  • valve means for enabling accumulated water to be drained from the unit.
  • Said support can be in the form of a coil spring with gaps between the turns of the spring, the gaps forming said perforations.
  • Said sleeve preferably comprises a coil spring with a removable lining of filter material in it.
  • the lining can be a polymer film or resin impregnated paper.
  • a fuel tank having a filler opening and a storage space for fuel, there being a water and solid contaminants retaining barrier through which fuel entering via the filler opening flows before reaching said storage space.
  • Said barrier is preferably in the form of a flexible sleeve which is closed at its lower end, the sleeve being secured in said filler opening and hanging down in said storage space.
  • barrier can comprise a sleeve extending from said filler opening downwards to the bottom of the tank, there being a drain opening in the bottom of the tank and a valve in the drain opening, the interior of the sleeve being in communication with said drain opening so that, when the valve is opened, water which has accumulated at the bottom of the sleeve drains out.
  • Said valve can be a manually operable tap which is accessible from the underside of the tank.
  • said valve comprises a valve element which is pressed against a valve seat by a spring, there being a pull cord which extends upwardly from said valve element, there being a pull ring for enabling an upward pull to be exerted on the valve element to lift the valve element from said seat against the action of the spring.
  • said barrier comprises a perforated outer support and a lining of filter material which can be removed from said support.
  • a sensor can be provided for detecting a water build up at the lower end of said sleeve together with an alarm which is activated upon said sensor detecting a water build up.
  • means for creating a sub-atmospheric pressure in the fuel tank can be included thereby to draw fuel through the barrier unit.
  • a method of removing water and contaminants from fuel which comprises placing a water and solids contaminants barrier between a filler opening of a fuel tank and the storage space of the fuel tank so that the fuel entering the tank through the filler opening passes through the barrier before reaching said storage space.
  • a method of filling a fuel tank which has a fuel inlet, a fuel storage space and a fuel outlet from said space connected by a fuel feed pipe to the fuel injection system of an engine, the method comprising feeding the fuel into said storage space of the tank through a water and contaminant removing barrier which is between said fuel inlet and said storage space.

There is a tap 18 in the opening 16. The tap is accessible from the underside of the tank 10.

  • the sleeve 14 further comprises a sheet material lining 22 inside the spring 20.
  • the lower part of the sleeve 14 is in the form of a bowl 24 for receiving water and contaminants that are retained by the lining 22.
  • the bowl 24 can be injection moulded and the end coil of the spring 20 can be embedded in the bowl during moulding.
  • the coil spring can be replaced by a perforated metal tube with the lining 22 inside it.
  • the lining 22 can be permanently secured to the metal sleeve or to the coil spring 20 or can be in the form of a sheath which is fitted into the sleeve and which can be removed if it becomes clogged.
  • the fuel entering the storage space in the tank 10 from the sleeve 14 is water and solid contaminant free.
  • the retained water sinks to the bottom of the sleeve 14 where it collects in the bowl 24 immediately above the drain opening 16.
  • the collected water can be allowed to flow to waste from the bowl.
  • a sensor can be provided which, upon it detecting a

  • the lower end of the sleeve 26 is closed by a bowl 32.
  • the fuel flowing in through the opening 12 enters the sleeve 26 and flows through the lining 30. Water and contaminants are retained. Once filling is complete, the sleeve 26 is removed from the tank 10, the water which has collected at the closed lower end of the sleeve in the bowl 32 tipped out and the tube dried for re-use.
  • Resin impregnated paper is a suitable medium which allows fuel to pass through it but retains water and solid contaminants.
  • Polymer films are also available commercially which will allow fuel to pass but will retain water and solid contaminants. Removing solid contaminants and water before the fuel reaches the in-line filters between the fuel tank and the engine has the effect of increasing the useful life of such filters.

  • a pull ring 66 is secured to the upper end of the cord 60 above the tube 64. So that it does not obstruct entry of the filler nozzle, it is desirable that the tube 64, or at least the upper part of it, be offset to one side of the sleeve 34.

Abstract

La présente invention a trait à un système de barrière qui est monté sur l'ouverture de la charge (12) d'un réservoir de combustible (10). Le système comprend un manchon extérieur (34) qui se présente sous la forme d'un ressort hélicoïdal (36) et un revêtement (38) qui est constitué d'un matériau qui permet au combustible de s'écouler à travers celui-ci mais qui retient l'eau et les contaminants solides. Une valve (52, 54) est prévue sur la partie inférieure du manchon (34) de manière à permettre à l'eau et aux contaminants solides accumulés d'être évacués du manchon (34).
